EDIT: I've had to remove my photos due to the actions of a small minority of immature individuals.

I suggest anyone that does not want their photos being misused and tampered with also removes them.

By uploading your images to a social website you do not lose the ownership of your material, so long as you are able to prove that it was created by you. Therefore, it is upto you to decide how that material is used, distributed and whether it may be copied.
